.To all whom it may concern:

Be it known t-hat I, ROBERT H. MILLER, a citizen of the United States, vand resident-of St. Louis, Missouri, have invented certain new and useful Improvements in Cleaning- Out Apparatus for Gas-Producer Connections, of which the following is a'specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to a cleaning out apparatus for gas producer connections, and the object of my invention is to provide means whereby the soot and like matter may be quickly and easily removed from gas producer connections and delivered into the stack, there to be drawn ofi by the natural draft therethrough.

Heretofore it has been the practice to open the manholes into gas producer connections, and pass suitable tools through said manholes to remove the soot from said connections. But this method requires much time and labor, and alsoallows air to pass into the interior of the connections,

which results in a combustion of the soot that is being removed from said connections. My improved means overcomes these objections, and stationary blowers are arranged which, when turned on, very quickly and efficiently remove the soot from the producer connections.

In the drawings-Figure 1 is a side elevation, partly in section, of a gas main leading from the producers, and showing my attachment connected thereto; Fig. 2 is an enlarged vertical section taken on the line 2 2 of Fig. l Fig. 3 is an enlarged section of the discharge end of one of the blowout pipes.

Referring by numerals to the accompanying drawings indicates the gas main that leads from the producer connection 2, and which main is constructed of a heavy sheet metal cylinder 3 that is lined with iire brick 4, or analogous material. The end of this main l, opposite from the end that leads from the producers, is provided with a tubular connection 5 that discharges into a conduit 6, that leads to and discharges into the stack.

Located at various points on the main l' l are manholes 7 norma y closed by doors 8, by means of which access rior of the main.

is had to the inte- Extending along beneath the main 1 is a pipe 9 that leads from a suitable source of steam supply. Connected. to and extending upwardly from this pipe 9, at suitable distances apart, are short tubes 10, in which are located suitable cut-ofi valves 11. Each pipe 10 is connected to a cross union 12, that is located immediately beneath the main 1 and leading` upwardly from this union are three pipes 13, the ends of which are extended through suitably formed apertures in the lower portion of the main, and the ends of these three pipes within the main are curvedtoward the end that discharges into the stack; and said ends are flattened, as indicated by 1.4, to provide narrow discharge o enings 15.

When it is desire to clean out the main 1, the first one of the valves l1 is opened, said first valve being the one nearest the producer connection 2, and upon opening said valve, steam from the pipe 9 passes upwardly through the pipe 10, through the branch pipes 13, and discharges from the flattened nozzles on the end thereof, which are upon the interior of the main l. These jets are defiected onto the body of the soot located in the end of the main l adjacent the connection 2, and said soot is forcibly driven toward the opposite end of the pipe. The operator now successively opens the cut-off valves 11 in the remaining pipes l0, and by so doing the soot is forced to the end of the main that discharges into the stack by means of the `tubular connection 5, and thus all of the soot in the main is finally blown into said stack from whence it is removed by the natural draft therethrough.

The steam discharging from the flattened ends of the pipes 13 supplies the volume which enables the stack to carry off the soot and like products, which said stack could not do otherwise, as a vacuum would be created unless the manholes were opened, or the producers kept under pressure.

My improved apparatus for blowing out the main does away with the necessity of opening the manholes. in said main, and thus prevents the combustion of the soot, and like products, and reduces the possibility of the brick lining in the main from being heated to such a degree as to injuriously aifect the shell by reason of the expansion and contraction of the brick.

The blowing out operation can very easily be accomplished by opening in sequence the series of cut-oil Valves, and thus much time and labor is saved, and the operation is completed much more eflectually than where suitable instruments are inserted through the manholes to remove the soot.

I claim 1. The combination with a gas producer connection, of a series of jet pipes arranged to discharge on the interior of said connection, the ends of which jet pipes are formed into liattened nozzles; and means arranged in each pipe whereby the discharge therefrom is controlled.

2. The combination with a gas producer connection, of a plurality of sets of jet pipes arranged to discharge into the connection, the ends ol' which jet pipes are formed into ilattened nozzles; and means whereby the discharge from each set of jets is controlled.

3. The combination with the main of a gas producer', of a series ol' sets of jet pipes discharging into the main, the ends ol' which jet pipes are formed into flattened nozzles;

means whereby the entire series of jet pipes are supplied from a single pipe, and means whereby the discharge from each individual set of jet pipes is controlled.

4. The combination with the main el' a producer connection, ol' a series oll sets oll jet pipes arranged to discharge on the interior ol' the main, the ends ol` which et pipes are formed into flattened nozzles, and means whereby the discharge `lrom any one or all el' the series of sets is controlled.

5. The combination with the main ol a producer connection, oiI a series ol jet pipes arranged to discharge on the interior ol said main, the ends olI which jet pipes are l'orined into attened nozzles; and means whereby the jet pipes may be opened successively so as to blow the accumulation in the 11min from one end thereoll to the other.

In testimony whereof, l have signed .lny

name to this specification, in presence ol' two A subscribing witnesses.
